Specification of Letters Patent.

Patented Aug. 16-, 1921.

Application filed October 11, 1919. Serial No. 330,092.

' following is a specification.

My invention relates to gas generating oil burners and particularly to a device of thls character patented to me on June 17 1919,

No. 1,307,20 I

The object of the invention isto improve the gas generating oil burner by the provision of a steam generator whereby steam vapor shall mix with the gas generated and the combined elements mixed with air, to produce a substantially perfect combustible mixture which shall burn and radiate great heat.

I attain this object and other advantages by means of the construction and combinaa gas retort assembled with the device.

tion of parts illustrated in the accompanying drawing in which-Figure 1, is a vertical section through the device embodying my invention, Fig. 2, is the same, and showFing 1g. 3, is a top plan view of the device shown in Fig. 1. Fig. 4-, is an end view of the nozzle for venting the combustible mixture and, Fig. 5, is an end View of the nozzle for venting steam vapor.

The device comprises a horizontally dl-S- posed plate 1, having a vertical flange on its upper side,at its peripheral edge. An annular vertical {flange 3, is formed centrally .on the upper side of the plate 1, and forms with the plate a basin 4:. Annular vertical flanges 5, are formed at opposite sides of the plate, in which the legs of a substan tially Ushaped tube 6, are placed and openings 30, in the base 1, allows fresh air to enter the tube. A tubular projection 7, is formed integral with the lower side of the arch of the tube 6, and communicates with the latter. An opening 8, is provided in the upper side of the tube 6, and is adapted for receiving the tubular stem 9, of a retort 10, or a steam pipe 11, as shown in Fig. 1. A mixing chamber 12, consisting of a cross sha ed coupling, is arranged to be stationed in t e arch of the tube 6, and its upper end is adapted for receiving the end of a steam pipe, in this instance pipe 11,- which conducts i steam from a hollow steam generating ring 14.-, to the mixer 12. A nozzle 15, having a diminutive orifice 16, is connected with the connected with the lower end of the mixer and arranged to vent combustible mixtures downwardly in the projection 7, of the tube 6. In the case of the device with the retort 10, the stem 9, thereof functions the same as the mixing chamber 12, to mix gas and steam, the air mixing with the product as before.

To operate the det'ice a quantity of oilis permltted to flow from the pipe 18, into the mixer 12,and to gravitate therefrom through the nozzles 15 and 19, to the basin 4,where the oil is ignited and allowed to burn. The flame thus produced effects a rapid heating of all the parts of the de ice and, eventually,

,the oil will be volatilized in the upperportion of the pipe 18, and the gas escape therefrom through the mixer and the nozzles 15 and 19. When gas is generated, the water in the pipe 17, is permitted to flow into the steam generating ring 14, in any suitable quantity, and the water striking the hot inner surface of the ring, is immediately converted into steam, in the well known manner. The-steam thus generated flows through the pipe 11, and through the nozzles 15 and 19, mixing in the latter with the gas from pipe 18, the mixture thus produced being discharged from the nozzle 19, into the extension 7, of the tube 6, where it'is further mixed with air flowing therethrough from the tube 6. The ultimate mixture of gas, steam, and air, 'in proportions limited' by the discharge orifices of the nozzles 15 and 19, and the capacity of the extension 7, of the tube 6, forms a combustible gas which wil burn with intense heat. compactness o the device adapts it for use in heating furnaces and stoves, in which the gevice may be placed on the usual grate ars.

The retort 10, shown in Fig. 2, is a provision for more rapid generation of gas, by introducin additional heated surface to receive the oil, and thereby obtaining greater quantity of gas. Y
